Objective To investigate rates and clinical associates of combined antipsychotic therapy in hospitalized patients with schizophrenia during 1986 ～ 2006. Methods Hospital charts of schizophrenic inpatients who discharged from six psychiatric hospitals in Tangshan in 1986,1996,2001, and 2006 were reviewed. Demographic and clinical character and prescription information at time of discharged of patients' was coded by trained investigators with a special designed form. Results The rates of combination antipsychotic therapy in the four years mentioned above were 13.2%, 18. 1% ,32.7%, and 28.9% ,respectively and the difference was statistically significant( x2 = 76.431, P ＜ 0.01; linear by linear x2 = 25. 542, P ＜ 0.01 ). Combined antipsychotic therapy in schizophrenic inpatients in Tangshan region show a increasing trend. There is significant difference of rate of combined antipsychotic therapy between hospitals. Combined antipsychotic therapy were associated with duration of illness,numbers of prior psychiatric hospital admission,hospital from which patients discharged,and discharged year.

Objective:To study the clinical effect of internal combined with external fixation in the treatment of pelvic fracture and its effect on the serum alkaline phosphatase (ALP),tumor necrosis factor-a (TNF-α) and transforming growth factor-β (TGF-β).Methods:Eighty-six patients with pelvic fractures admitted in our hospital from August 2014 to July 2015 were selected and divided into the observation group and control group according to the admission order.Conventional internal fixation was used in the control group,and the internal combined with extemal fixation was performed in the observation group.The clinical curative effect,operative time,blood loss,fracture healing time and incidence of complication were compared between two groups.The levels of serum ALP,TNF-α and TGF-β in the two groups were compared before and after treatment between two groups.Results:The excellent rate of observation group was significantly higher than that of the control group [81.40％ (35/43) vs 41.86％ (18/43)] (P ＜0.05).The operative time,blood loss and fracture healing time in the observation group were significantly shorter or less than those of the control group (P＜0.05).There was no significant difference in the serum ALP,TNF-α and TGF-β levels between the two groups before treatment (P＞0.05).After treatment,the serum ALP levels in the two groups were significantly higher than before treatment (P＜0.05).The levels of TNF-α and TGF-β were significantly lowe than those before treatment(P＜0.05),the ALP levels in the observation group was significantly higher than that of the control group (P ＜0.05),and the levels of TNF-c and TGF-β were significantly lower than those of the control group 0.05).The incidence of complications of observation group was significantly lower than that of the control group [0.00％ (0/43) vs 11.63％ (5/43)] (P ＜0.05).Conclusion:Internal and external fixation was effective and safe in the treatment of pelvic fractures,which could significantly increase the serum ALP level and reduce the levels of TNF-α and TGF-β.

Objective To understand the occurrence situation of negative life events in the past year among college students with suicidal ideation and to explore the correlation between negative life events and suicidal ideation. Methods The stratified and cluster sampling method was applied to conduct the questionnaire survey on 12 114 students from 11 universities in Chongqing City. The questionnaire of general demographic information was used to learn sociodemographic characteristics;the perspective on personal life questionnaire was applied to evaluate the suicidal ideation within recent 1 month and the self-designed life event scale was used to investigate the occurrence of negative life events in the past 1 year. Results The report rate of suicidal ideation within 1 month was 9.6%, the occurrence rate of short term suicidal ideation was increased with experiencing more negative life events. The x2 test showed that there was statistically significant difference in the proportion of suicidal ideation occurrence between college students experiencing 1 negative life event and those without experiencing the negative life event (x2 = 37.72,P<0.01) ;besides, the occurrence proportion of recent suicidal ideation had statistical difference between the college students with experiencing two or more negative life events and those without experiencing negative life event (x2 = 65.46,P<0.01). The multivariate Logistic regression analysis showed that the conflict with other family members (OR=0. 295,95%CI 0. 017-0. 571),abuse (OR=7. 295, 95%CI 6. 049-9. 701) were independentrisk factor for the recent suicidal ideation in college students. Conclusion Experiencing more negative life events, conflicting with other family members and abused by others have a correlation with the appearance of short term suicidal ideation in college students.

BACKGROUND:As a routine method after lumbar spine surgery,a drainage tube is convenient for postoperative bleeding drainage and management,and there is still no consensus on the choice of postoperative removal time for short-segment lumbar spine surgery with less risk. OBJECTIVE:To explore the effect of different drainage times on early clinical efficacy after short-segment lumbar fusion. METHODS:A prospective randomized controlled study was performed on 220 patients in the Affiliated Hospital of Southwest Medical University who underwent posterior lumbar interbody fusion for lumbar degenerative diseases from March 2017 to April 2021.According to the different drainage times,the patients were randomly divided into removal on the second day after operation(group A),removal on the third day after operation(group B),and removal after the observation method 24-hour drainage volume<30 mL(group C).The perioperative indicators and follow-up results of the three groups of patients were observed and compared. RESULTS AND CONCLUSION:(1)Because 7 patients were lost to follow-up,2 patients were excluded,and 211 patients were finally included(72 patients in group A,71 patients in group B,and 68 patients in group C).(2)The average drainage time of group C was 2.91 days.The postoperative drainage volume in group A was significantly less than that in groups B and C,and the difference was statistically significant(P<0.05).On day 3 after operation,the hematocrit value of group C was lower than that of group A and group B,and the difference was statistically significant(P<0.05).Postoperative activity time and hospital stay in group A were shorter than those in groups B and C,and the difference was statistically significant(P<0.05).(3)Four patients in group A,two patients in group B and three patients in group C received an allogeneic blood transfusion.There was no significant difference among the groups(P>0.05).(4)In terms of postoperative complications,there were no statistical differences in postoperative wound leakage and surgical site infection in all three groups(P>0.05).(5)All patients were followed up for more than 12 months.Visual analog scale score and Oswestry dysfunction index of the three groups of patients before discharge and at the last follow-up were significantly improved compared with those before surgery(P<0.05).There was no statistical significance among the groups(P>0.05).(6)It is indicated that the removal of the drainage tube on the second day after a posterior lumbar fusion can effectively reduce the time to get out of bed and hospital stay,without increasing the postoperative blood loss and the risk of complications.

BACKGROUND:Some patients with cervical spondylosis have not been fully corrected sagittal position balance after cervical surgery,and this continuous sagittal position imbalance may be an important reason for the poor long-term clinical outcome of patients. OBJECTIVE:To analyze the correlation between the cervical sagittal position balance parameters and their changes and the clinical efficacy of patients in the unbalanced state after anterior cervical decompression and fusion and to explore the necessity of surgical correction of sagittal balance in order to improve the clinical effect in the later stage. METHODS:A retrospective analysis was performed on 125 patients with cervical spondylosis who underwent anterior cervical decompression and fusion in the Department of Spinal Surgery of Affiliated Hospital of Southwest Medical University from July 2019 to July 2022.Follow-up patients had good postoperative recovery(neck disability index score less than 10%one week after surgery)and had complete follow-up data.According to the axial vertical distance(C2-7 SVA)in sagittal position one week after surgery,patients were divided into type I imbalance group(C2-7 SVA loss≤5 mm,n=27),type Ⅱ imbalance group(C2-7 SVA loss>5 mm,and≤10 mm,n=19),and type Ⅲ imbalance group(C2-7 SVA loss>10 mm,n=12),and non-unbalanced group(C2-7 SVA in the normal range,n=67).The changes of visual analog scale score and neck disability index were compared among groups postoperatively and the last follow-up,as well as the changes of imaging sagittal balance parameters C2-7 cobb angle,C2-7 SVA value,neck inclination angle,T1 inclination angle,and thoracic entrance angle.The correlation between the late clinical effect and postoperative cervical sagittal disequilibrium was explored. RESULTS AND CONCLUSION:(1)There was no statistical difference in general data among the four groups(P>0.05).All patients underwent successful surgery without serious complications and postoperative wound infection.The follow-up time was more than 1 year.(2)There was no significant difference in preoperative symptom score and clinical efficacy one week after surgery(P>0.05).At the last follow-up,pain visual analog scale score,neck disability index and C2-7 SVA were lower than those before surgery but higher than those one week after surgery(P<0.05).C2-7 cobb angle was increased compared with those before operation(P<0.05).T1 inclination angle was decreased compared with those before operation(P<0.05).(3)Pearson correlation test showed that the change of neck disability index was positively correlated with the change of C2-7 SVA(P<0.05).(4)It is indicated that anterior cervical decompression and fusion is effective in the treatment of cervical spondylosis,and can effectively relieve the symptoms of patients.Patients with more severe cervical sagittal disequilibrium after surgery had worse curative effect in the later period.Continuous sagittal disequilibrium in patients with cervical spondylosis after surgery is an important cause of poor curative effect in the later stage.Clinicians should pay more attention to the correction of cervical sagittal balance before and during surgery,formulate surgical strategies and plans according to sagittal balance parameters before surgery,and correct C2-7 SVA intraoperatively to the normal range.

【Objective】 To establish a novel localization method for sacral nerve foramen puncture by analyzing the characteristic of sacral nerve foramen trying to help improve the success rate of sacral foramen puncture. 【Methods】 Clinical data and sacrococcyx CT and three-dimensional reconstruction imaging data of 158 patients who received sacral nerve modulation (SNM) during Jan.2019 and Aug.2022 in our hospital were retrospectively analyzed.The distance between inferior margin of articulatio sacroiliaca and the internal edge of the 3rd neural foramen (D1), and the distance between the internal edge of the 3rd neural foramen and sacral midline (D2) were measured, and the ratio of D1 and D2 was calculated for precise intraoperative positioning. The measurement data characteristic and puncture results were analyzed. 【Results】 A total of 89 males and 69 females were included, with an average age of (49.0±16.9) years.The average D1, D2, and D1/D2 were (29.6±4.9) mm, (13.8±3.2) mm, and (2.2±0.6), respectively.Female patients had greater D1 \[(30.7±5.5) mm vs.(28.7±4.2) mm, P=0.010\] and D1/D2 \[(2.4±0.7) vs.(2.1±0.5), P=0.001\] than male patients.Compared with adults, the adolescents had smaller D1 \[(29.8±4.7) mm vs.(25.7±5.4) mm, P=0.006\].After precise intraoperative positioning using this positioning method, 158 patients were successfully punctured, 152 (96.20%) had excellent intraoperative neural response, 2 (1.27%) had good response, and 4 (2.53%) had average response. 【Conclusion】 The surface projection of sacral nerve was approximately at the middle-inner 1/3 of the inferior margin of articulatio sacroiliaca to sacral midline.Through measuring distance from inferior margin of articulatio sacroiliacato sacral midline via X-ray, sacral nerve situation could be performed in surface, which might be a secure way to accessorily situate electrode implantation site for sacral neuromodulation.

Osteoporotic thoracolumbar fracture in the elderly will seriously reduce their quality of life and life expectancy. For osteoporotic thoracolumbar fracture in the elderly, spinal reconstruction is necessary, which should comprehensively consider factors such as the physical condition, fracture type, clinical characteristics and osteoporosis degree. While there lacks relevant clinical norms or guidelines on selection of spinal reconstruction strategies. In order to standardize the concept of spinal reconstruction for osteoporotic thoracolumbar fracture in the elderly, based on the principles of scientificity, practicality and progressiveness, the authors formulated the Clinical guideline for spinal reconstruction of osteoporotic thoracolumbar fracture in elderly patients ( version 2022), in which suggestions based on evidence of evidence-based medicine were put forward upon 10 important issues related to the fracture classification, non-operative treatment strategies and surgical treatment strategies in spinal reconstruction after osteoporosis thoracolumbar fracture in the elderly, hoping to provide a reference for clinical treatment.

OBJECTIVE: To investigate the development present situation of the department of critical care medicine in Inner Mongolia Autonomous Region (hereinafter referred to as Inner Mongolia), in order to promote the standardized and homogeneous development of critical care medicine in Inner Mongolia, and also provide a reference for discipline construction and resource allocation. METHODS: A survey study was conducted in comprehensive intensive care unit (ICU) of tertiary and secondary hospitals in Inner Mongolia by online questionnaire survey and telephone data verification. The questionnaire was based on the Guidelines for the Construction and Management of Intensive Care Units (Trial) (hereinafter referred to as the Guidelines) issued by the National Health Commission in 2009 and the development trend of the discipline. The questionnaire covered six aspects, including hospital basic information, ICU basic information, personnel allocation, medical quality management, technical skill and equipment configuration. The questionnaire was distributed in September 2022, and it was filled out by the discipline leaders or department heads of each hospital. RESULTS: As of October 24, 2022, a total of 101 questionnaires had been distributed, 85 questionnaires had been recovered, and the questionnaire recovery rate had reached 84.16%, of which 71 valid questionnaires had been collected in a total of 71 comprehensive ICU. (1) There were noticeable regional differences in the distribution of comprehensive ICU in Inner Mongolia, with a relatively weak distribution in the east and west, and the overall distribution was uneven. The development of critical care medicine in Inner Mongolia was still lacking. (2) Basic information of hospitals: the population and economy restricted the development of ICU. The average number of comprehensive ICU beds in the western region was only half of that in the central region (beds: 39.0 vs. 86.0), and the average number of ICU beds in the eastern region was in the middle (83.6 beds), which was relatively uneven. (3) Basic information of ICU: among the 71 comprehensive ICU surveyed, there were 44 tertiary hospitals and 27 secondary hospitals. The ratio of ICU beds to total beds in tertiary hospitals was significantly lower than that in secondary hospitals [(1.59±0.81)% vs. (2.11±1.07)%, P < 0.05], which were significantly lower than the requirements of the Guidelines of 2%-8%. The utilization rate of ICU in tertiary and secondary hospitals [(63.63±22.40)% and (44.65±20.66)%, P < 0.01] were both lower than the bed utilization rate required by the Guidelines (75% should be appropriate). (4) Staffing of ICU: there were 376 doctors and 1 117 nurses in tertiary hospitals, while secondary hospitals had 122 doctors and 331 nurses. There were significant differences in the composition ratio of the titles of doctors, the degree of doctors, and the titles of nurses between tertiary and secondary hospitals (all P < 0.05). Most of the doctors in tertiary hospitals had intermediate titles (attending physicians accounted for 41.49%), while most of the doctors in secondary hospitals had junior titles (resident physicians accounted for 43.44%). The education level of doctors in tertiary hospitals was generally higher than that in secondary hospitals (doctors: 2.13% vs. 0, masters: 37.24% vs. 8.20%). The proportion of nurses in tertiary hospitals was significantly lower than that in secondary hospitals (17.01% vs. 24.47%). The ratio of ICU doctors/ICU beds [(0.64±0.27)%, (0.59±0.34)%] and ICU nurses/ICU beds [(1.76±0.56)%, (1.51±0.48)%] in tertiary and secondary hospitals all failed to meet the requirements above 0.8 : 1 and 3 : 1 of the Guidelines. (5) Medical quality management of ICU: compared with secondary hospitals, the proportion of one-to-one drug-resistant bacteria care in tertiary hospitals (65.91% vs. 40.74%), multimodal analgesia and sedation (90.91% vs. 66.67%), and personal digital assistant (PDA) barcode scanning (43.18% vs. 14.81%) were significantly higher (all P < 0.05). (6) Technical skills of ICU: in terms of technical skills, the proportion of bronchoscopy, blood purification, jejunal nutrition tube placement and bedside ultrasound projects carried out in tertiary hospitals were higher than those in secondary hospitals (84.09% vs. 48.15%, 88.64% vs. 48.15%, 61.36% vs. 55.56%, 88.64% vs. 70.37%, all P < 0.05). Among them, the placement of jejunal nutrition tube, bedside ultrasound and extracorporeal membrane oxygenation were mainly completed independently in tertiary hospitals, while those in secondary hospitals tended to be completed in cooperation. (7) Equipment configuration of ICU: in terms of basic equipment, the ratio of the total number of ventilators/ICU beds in tertiary and secondary hospitals [0.77% (0.53%, 1.07%), 0.88% (0.63%, 1.38%)], and the ratio of injection pump/ICU beds [1.70% (1.00%, 2.56%), 1.25% (0.75%, 1.88%)] didn't meet the requirements of the Guidelines. The equipment ratio was insuffcient, which means that the basic needs of development had not been met yet. CONCLUSIONS The development of comprehensive ICU in Inner Mongolia has tended to mature, but there is still a certain gap in the development scale, personnel ratio and instruments and equipment compared with the Guidelines. Moreover, the comprehensive ICU appears the characteristics of relatively weak eastern and western regions, and the overall distribution is uneven. Therefore, it is necessary to increase efforts to invest in the construction of the department of critical care medicine.
